Description

Floor power supply device

Technical field

The present invention relates to open the door of making by insulator, make be embedded in underground electrode from ground (road surface) stretched head, to covering the electric installation supply capabilities such as electric car of this electrode.In use, close, do not have concavo-convex with the insulator door, the inflow of foreign material is few in addition, can carry out maintenance, because be not have the constructive mechanism and the control of getting an electric shock, so can in the power supply of the streetcar at urban district or scenic spot etc., utilize based on regular washing and air purging device.Electric car system does not in the past have track according to metal screw mandrel and stringing, occasion, and it is little to carry capacitance of storage, can realize light weight and cheap traffic system.In addition, can power with device, electric excavator, electric crane, special lighting device to cruiser, disaster.

Background technology

In the past,,, the cylinder of burying underground based on air or electricity underground was arranged, drove 2 contacts up and down, the method for powering from the road surface stretched head from the stringing of electric car or the method for power supplying beyond the power supply of electrical connector on the ground as outdoor., in the method, in the time of in immersing rainwater or mud, the electrical accessory of cylinder etc. might et out of order.There are a lot of systems not block the mechanism in the ground-surface hole of stretched head.In addition, when non-power supply, not that contact fully sinks to underground structure, insufficient on preventing to get an electric shock., there is the electromagnetic threat that can't see in the noncontact method that induction coil etc. sink to underground power supply, and the manner is simple, but mechanism smooth for the ground surface part and that do not get an electric shock, so the third parties such as pedestrian have the sense of security.

Summary of the invention

At first, problem as in the past floor power supply device can list: further be particular about the countermeasure that prevents to get an electric shock, eliminate the mechanism that buries underground owing to immerse the misoperation that causes in the rainwater or contact or the breakage of insulator door that the misoperation of tangling the machinery that causes of foreign material, the bump that makes maintenance become easily, not take place foreign matter such as handstone merely cause.

As the electric shock countermeasure, when adopt to remove using, use the door that constitutes by insulator to cover the hole of contact discrepancy, the mechanism that is difficult to open.As immersing in the rainwater, one of countermeasure of misoperation, except the method for burying water repellant electrical accessory underground, away from the place for example on the curb consumer unit is set, leave in wherein.Particularly, deposit electric circuit 200 (feed circuit, control circuit), cylinder or motor.Employing forms inclined-planes with insulator door 112 in power supply, prevent the breakage of the contact that the bump of foreign matter causes, when impact was strong, insulator door and contact sank to underground structure jointly.The function of performance circuit, just think vehicle etc. near the time, open the insulator door, the contact stretched head only when contact contacts with the other side fully, is powered.

According to the present invention, can realize preventing the big surface power supply of effect that gets an electric shock and stop foreign material to flow into.Can not become ground-surface concavo-convex obstacle,, have durability yet, can not worry to get an electric shock rainwater, thus can on the road surface, be provided with, even without metal screw mandrel or stringing, also can be to the electric car automatic power.In stringing in the past, purposes almost is limited on the electric car, if but according to the manner, then streetcar not only also can use this device in EV car (electric city motor bus, electric car, wheelchair).

The specific embodiment

Fig. 1 isolates the cross section skeleton diagram of the portion of mechanism of a side on the ground to electrical accessory from waterproof.In Fig. 1, the 100th, consumer unit, the 101st, cylinder or motor, the 102nd, metal filament, the 103rd, operating spring up and down, the 104th, last push roller, the 105th, lower compression roller, the 106th, contact, the 107th, basic bar, the 108th, spring, the 200th, electric circuit (feed circuit, control circuit etc.), the 201st, charge circuit, the 202nd, cond (or storage battery), the 203rd, input is subjected to electric wire, and the 204th, supply line, the 300th, the cross section of electric car, the 301st, be subjected to electric body, the 302nd, wheel.

If with reference to Fig. 1 action is described, then at first cylinder 101 resembles stretched wire 102 arrow, and basic bar 107 just is moved to the left, because operating spring 103 up and down, contact 106 rises stretched head.Then, electric car 300 is close, if be subjected to 2 groups of electric body 301 all with 2 groups of normal terminations of described contact 106, then the electric circuits 200 in the consumer unit 100 make main switch 216 conductings, the electric power that is subjected to electric wire 203 acceptance by input is offered by contact 106 be subjected to electric body 301.If electric car 300 is away from this place, just left by electric body 301 from contact 106, if cylinder 101 is lax metal filament 102, then basic bar 107 is owing to the power of spring 108 moves right, up and down operating spring 103 lower compression roller 105 to pressing down, contact 106 sinks to underground from the road surface, electric circuit 200 disconnects main switch 216, ends power supply.

In above method, even consumer unit 100 and contact 106 leave cooresponding distance, or be positioned at can not be with till the straight line bonded assembly configuration, if use metal filament and pulley, contact 106 just can easily move up and down, the displacement that causes for muddy water or disaster in addition, it is bad also to be difficult to become action.

Fig. 2 is other examples in the cross section of portion of electric supply installation of the present invention mechanism.In Fig. 2, the 109th, the drop-down pulley of using all is fixed on the housing.Other symbols are identical with Fig. 1.If with reference to Fig. 2 action is described, then drawing metal on the cylinder 101 upwards draws terminal 111, as shown in Figure 2, contact 106 is from the ground stretched head, in addition as shown in Figure 2, in this position, electric car 300 covers, and when all normally contacts with contact 106 by 2 groups of electric body 301,200 pairs of electric cars of electric circuit 300 are powered, when having cond 202, by 202 chargings of 201 pairs of conies of charge circuit (when quickening, not only charging also can utilize power supply electric power in acceleration).

Fig. 2 is for the cross section of electric car about 300, and Fig. 3 is the simplified schematic cross-sectional view for front and back.Here, can still as shown in Figure 3, can block in the cracking seam hole, place that contact 106 is come in and gone out from ground with the door that forms by one-sided opening or the open insulator 112 of bilateral.As shown in Figure 3, contact 106 rises, if stretched head, then insulator 112 is that open at the center with fulcrum 113.As a result, can be from contact 106 to being subjected to 301 power supplies of electric body, in addition, and because door is oblique, thus even run into remains, also drop on the inclined-plane, so the breakage of contact 106 is few.Usually, after vehicle passed through, cylinder 101 was lax metal filament, so pass through the tension force of spring 108, contact 106 is embedded in underground, can prevent from fully to get an electric shock.Insulator 112 becomes the form of closing the door, so can not become the ground-surface obstacle, foreign material are difficult to flow into.

, in described explanation, contact 106 moves up and down, and stretched head, but replace contact 106 can adopt noncontact style such as inductance coil at the underground structure that moves up and down.In addition, also can not that metal filament moves up and down contact 106, but the joint of L font is set,, become 0 degree or 90 degree, thereby contact 106 is moved up and down by the tension force of metal filament 102.

Fig. 4 is other examples of mechanism's cross section summary, puts down in writing the example of main insulator door of the present invention.At first, the 306th, be similar to from the thing of the drain cover of just popularizing in the past, be accompanied by drain gutter 305.The top that has the casing 120 of

insulator door

112 and 114 on top is embedded in the drain gutter 305, and the bottom is crimped on the inboard of drain cover 306 by on spring 119 by drg 117.

Insulator door 112 is the center with fulcrum 113, and to horizontal extension, but a part is extended the bottom 114 of formation insulator door downwards.In Fig. 3, the bottom of contact 106 is pressed the bottom 114 of the described insulator door of tooth to the left and right, so be fulcrum 113 center, as seesaw, described insulator door 112 is closed, and can't open easily.Be the wheel friction, mischief can not opened, and does not have foreign material and flows into.On the contrary, if described contact rises, then insulator door 112 is opened as shown in Figure 3, described contact 106 stretched heads.At this moment, the bottom 114 of insulator door intersects, and passes the window 116 of the contact of Fig. 4.Above mechanism is one of the present invention.

So, described contact 106 is when the state of stretched head (Fig. 3), when running into handstone or foreign matter, insulator door 112 forms inclined-planes, so that contact 106 is avoided is damaged, but when the impact of handstone etc. is strong, because spring 119, casing 120 all sinks to, and avoids the breakage of each several part.This is second invention.

The 115th, guide rail or bearing are used to make contact 106 successfully to move up and down.When the rising of contact 106, undertaken by the rotation of metal filament and pulley 109, when descending, undertaken by the rotation of metal filament and pulley 110.But replace them, drip proof machine can be set, contact 106 is moved up and down.In addition, can replace contact 106, adopt induction coil is installed, become the non-contact type administration of power supply different with the manner.

Below, the structure and the action of electricity are described.Fig. 5 is the synoptic map of electric circuit 200.If action is described,,, arrive electric supply installation one side then as aerial signal ripple 303 if then at first send from carrying power requirement signal at the signal transmitter 304 of vehicle one side (electric wave, sound wave can, for example the frequency of 40Khz) according to Fig. 5.

If this signal rectification, just this intensity and certain fixed value are compared by comparator 207, if big, just described contact risen to from the face of land and lean out head by cylinder or motor.

On the contrary, if littler, described contact 106 is descended (be called near detecting and handle) than eigen value.The signal of the projector 206 of electric supply installation one side (for example 50Khz) when contact 106 when contacted fully by electric body 301, the resonance frequency of C1, L1 and C2, L2 is 50KHz, so when by them, voltage does not take place descend.Therefore, the output of comparator 208 just becomes, and makes semiconductor switch GTO conducting, powers.If contact 106 with not exclusively contacted by electric body 301, then the output of comparator 208 becomes negatively, and GTO is disconnected, and stops power supply.Also powering when not exclusively contacting causes spark, so spark is few in above processing.In addition, during power supply, when contact is covered by vehicle, prevent to get an electric shock.These signal conditioning also can be carried out in microcomputer.

As mentioned above, according to the present invention, can realize not worrying getting an electric shock, anti-rainwater and foreign material even be provided with on the way, also can not become the floor power supply device of obstacle.
